So many non-optimal combos.
I know you might look at the sjc one-charge, and think "it only does 200 more, so why use it?" It doing 200 more is enough to decide matches. And, when it comes time to do corner combos, 6C>jc j.bc>j.cc won't cut it after 22D. You won't get the height you need to continue the corner combo into a delicious 4.4k. It's better that you get used to it now. And that one time you dp'd ater 22D, I cringed. You lost so much damage. IF you thought you were too far away from midscreen for the combo to carry, or something, you can dash after 22D to get close enough to midscreen.
j.236x is mad unsafe by itself.
Toss out 2C as an anti-air. Most of Tsu's normals are bad, but 2C is really, really good. Use it, especially as opposed to going air-to-air. (j.B stuffs some stuff, but not much. 2C is much less risky.)
